The effects of forest thinning on the food-based carrying capacity of a mixed oak forest for white-tailed deer in the ridge and valley province of Virginia
… Province of Virginia to provide the seasonal digestible protein and energy requirements of a white-tailed doe following a commercial thinning operation was evaluated. The element of time elapsed since thinning was emphasized and was represented by three contiguous forested parcels thinned over …

Effects of energy and protein levels on attainment of puberty and steroid hormone production in captive female white-tailed deer
… to one of four treatments with that group. High energy-high protein (HEHP), high energy-low protein (HELP), low energy-high protein (LEHP), and low energy-low protein (LELP) diets were the treatments used in 2x2 factorial design. High energy diets contained an average of 3064 kcal/kg digestible …

Photoperiod and nutritional influences on reproduction, growth and pelage changes in the pine vole
… chow diet supplemented with apple consumed less digestible energy but had higher body weights and more body fat, and males had heavier testes than those fed only chow. Adults on a 14L:10D photoperiod had higher values for reproductive characteristics than those on a declining photoperiod. In a …

The Utilization of Dietary Fiber and Its Effects on The Utilization of Other Dietary Components by Swine
… detergent fiber (ADF), hemicellulose (H) and digestible energy (DE) by growing swine. For weanling pigs, fecal N excretion was increased and N retention was decreased by the addition of either of three commercial cellulose products to a 15% cornstarch-casein diet. Cellulose additions to a 9% …

The trend towards sociality in three species of southern African mole-rats (Bathyergidae) : causes and consequences
… factors together with the size, distribution, digestible energy and fibre content of the geophytes on which they feed and nearest-neighbour distances occurring between the belowground portions of the geophytes, may be crucial in determining whether a habitat is suitable for solitary or colonial …

Digestibility of Two Complete Pelleted Diets by the Horse (Equus caballus) as a Model Animal for Nondomestic Hindgut Fermenters
<p>Estimating nutrient and energy requirements of exotic animals is a necessary component of nutrition management in zoos and other wildlife facilities. In the absence of species-specific data, domestic animal models are often referenced. Herbivorous hindgut fermenters, such as horses, zebra, and …

The Suitability of Native Warm-Season Grasses for Equine
… in Virginia's grasslands, but their high digestible energy and non-structural carbohydrate (NSC) levels pose a risk for horses prone to obesity and laminitis. Native warm-season grasses (NWSG) have lower digestible energy and NSC levels that may be more suitable for horses susceptible to …

Studies on the nutritional value of poultry litter in ruminants and poultry
… 10 yearling wethers to study the protein and energy utilization of autoclaved peanut hull and woodshaving broiler litters when each was incorporated in corn-hay natural ration at levels of 25 and 50 percent. Apparent digestibility of crude protein did not show any significant difference among …

Intake and Digestibility of Brown-Midrib Corn Silage by Lactating Dairy Cows
… cell-wall contents, acid detergent fiber, and energy were 3 to percentage units higher for the bm<sub>3 </sub>ration. Milk yield was not affected by ration, but milk fat percentage was higher for cows fed the bm3 ration. Total ruminal volatile fatty acids, pH, and ammoniacal nitrogen levels …

Feeding Value of High Protein Oat Silage Versus Corn Silage for Dairy Cows
… higher crude protein and a higher percent of digestible protein than corn silage, sorghum silage, and barley-pea silage. However, corn silage is superior to oat silage in total digestible nutrients (TDN) and digestible energy (17, 56, 96). The protein yield in oat groats (dehulled kernels) of …

Description and commissioning of a novel swine calorimeter unit to calculate heat production and net energy in group-housed pigs
Values for digestible energy (DE), metabolizable energy (ME) and net energy (NE) are used to develop prediction equations for diet formulation, usually calculated from data for individually housed pigs. However, pigs in commercial conditions are usually housed in groups and allowed ad-libitum feed …
